Abstract:
Nanotechnology has long left the laboratory and its discoveries and products are all around us -- from longer lasting tennis balls, waterproof pants and drug delivery patches to quicker and more powerful computers, and faster burning rocket fuels. Last year alone, nano-business garnered $32 billion in sales of household products in the U.S.

Using nanotechnology, scientists have found ways to manufacture molecules - - some of the smallest building blocks of nature -- and put them together a few at a time. According to many experts, nanotechnology is triggering a revolution in building materials that is radically changing science and technology.
